Title: Synthesis of substituted triphenylenes useful for discotic liquid crystals
Inventor: BUSHBY RICHARD JAMES
IPC: G02F1/13
Filed: 1994-06-13
Abstract: Substituted triphenylenes, required in the synthesis of polymeric discotic liquid crystals, are made using an oxidising agent (eg FeCl3 or NOBF4) to couple suitably substituted benzenes with suitably substituted benzenes or biphenyls. The coupling is followed by treatment with a reducing agent (eg methanol). For example, iron (III) chloride in organic solvent at room temperature may be used to effect the oxidative coupling of 1,2-dialkoxybenzenes to 3,3',4,4'-tetraalkoxybiphenyls. The same oxidation-reduction protocol also proves effective in the trimerisation of 1,2-dialkoxybenzenes.

Abstract: A high-side switch such as a MOSFET 20 or an IGBT has a control MOSFET 53 of reduced threshold voltage connected between its gate and source. The input signal applied to transistors 66 and 27 is level shifted by Zener diode 70 and resistor 60, inverted by transistor 63, then applied to the control transistor 53. This allows the input signal to retain control of the switch 20 even during negative clamping, and prevents turn-on when the supply voltage is low and the output is negative.
Patent GB-2305748-A (GB)
Title: Logging updated disk sectors
Inventor: OKADA HIDEAKI
IPC: G06F3/06
Filed: 1996-07-03
Abstract: Updating log recording driver 6 maintains two updating logs, A and B, which indicate which areas of disk 5 have been written to. Log A is less detailed than larger log B in that each log B entry corresponds to a smaller area of disk 5. The logs are updated when the computer writes to disk 5. Small log A is backed up to the log recording disk unit 7 whenever log A is updated and log B is backed up at predetermined times. The updated portions of disk 5 are periodically backed up to tape using log B in the computer's memory. Should a system fault occur then the back up process uses the version of log B on the log recording disk unit 7, or if this is not current, log A. The logs may be extended, making them more detailed, and/or only a part of log B may be held in the computer's memory, conserving space.
